space time (τ = v/q), which is the mean reaction time available for the reacting species
to undergo reaction in the vessel volume. The extent of conversion achieved within the
available reaction time depends on the rate of reaction and the level of uid mixing (tur-
bulence) that is prevalent in the reactor volume. Fluid mixing is achieved with the help
of an agitator in the CSTR and by maintaining turbulant ow conditions in the tubular
reactor. Appropriate design of a homogeneous reactor requires a deeper understanding of
the uid mixing pattern and its effect on the reaction and will neces
